previous route. Of plants not elsewhere noticed may be men-. 
tioned Sphæralcea acerifolia Nutt. and Rudbeckia occidentalis 
Nutt. Near the summit of the high rocky peak overlooking Snake — 
and Wind River valleys was found a new species of Draba char- 
acterized by Dr. Gray, under the name of Draba ventosa n. SP. 
(see Appendix, No. 15): also Aster montanus Rich, the latter only 
known from high northern collections in British America. 
From this accessible pass, by which the Yellowstone Park can 
be reached on a very direct route, we passed rapidly down the open 
valley of Wind River and reached our previous rendezvous at 
Camp Brown, on September 12th, after just two months’ absence.

Tue ZoorocicaL Record ror 1871.*—To those who live away 
from libraries and would keep themselves informéd; as: to the an- 
nual progress in any department of descriptive zoology, this record / 
is invaluable. Working naturalists, also, more favorably situated, 
cannot do without it. We have found but few omissions in it, and, l 
American articles and memoirs are faithfully reported. The ae 
volume has been slow in making its appearance, and we hope e better 
fortune and better health will fall to the lot of the asi and his 
assistants in the preparation of the volume for 1872.
